Antagonists

Characters who oppose the protagonists in the SuperMarioLogan franchise/videos.

Note: Although a villain is an antagonist, an antagonist and a villain are not always the same term since not all antagonists are necessarily villains. In fact, some of these characters in SML videos are not evil, but they are still antagonists as they antagonize the protagonists. Also, a few characters in the SML franchise that are in this category are considered protagonists, but they can be considered antagonists on some occasions.
